Olsen, Park Ridge, 11]., assignor to Carstens Manufacturing Company, Norridge, Ill., a corporation of Illinois Filed Jan. 5, 1968, Ser. No. 695,914 Int. Cl. A47f /01, 7/16; A47b 63/00 US. Cl. 211-45 12 Claims ABSTRACT OF THE DISCLOSURE A portable hospital record chart holder apparatus is provided which includes a wheel-bearing frame which includes means for supporting hospital record chart holders suspended vertically. To prevent the hospital record chart holders from swinging on their supporting shaft or pintles and clashing into contact with each other, with resulting noise, stationary resilient snubber bar members are mounted on the supporting frame at the outer sides of the record chart holders. Additional resilient manually operable snubber bar members are slidably mounted on the supporting frame and are laterally movable thereon by means of a manually operable slide bar so as to urge the slidably mounted snubber bar members into snubbing engagement with the inner edge portions of the record chart holders and thus snub the record chart holders between the stationary resilient snubbing bar members and the slidably mounted snubbing bar members, and thus hold the suspended record chart holders firmly against swinging movement on their supporting shafts or pintles as the new portable hospital record chart holder is moved or rolled on its supporting caster wheels through the aisles or hallways of hospitals and like places. In this manner the clashing noise caused by the swinging movement of prior suspended record chart holders on their supporting shafts or pintles as the record chart holders are rolled from place to place in the hallways of hospitals, and like places, is eliminated.

Objects An object of the invention is to provide a new and improved portable wheel-bearing hospital record chart holder on which hospital record charts are suspended in a vertical position and which, in use, prevent the hospital record chart holders from swinging and clashing with resulting objectionable noise as the wheel-bearing hospital record chart holder is moved from place to place through the hallways of hospitals and the like.

Another object of the invention is to provide in the new portable hospital record chart holder novel manually operable portions of the record chart holders and thus snubbing them between the slidably mounted snubber .bar members and the resilient snubber bar members which are stationarily mounted on the supporting frame on the laterally outer sides of the record chart holder so as to prevent swinging movement of the record chart holders on their supporting shafts or pintles and thereby eliminating the noise caused by the clashing of such hospital record chart holders on their supporting shafts or pintles when such a wheel-bearing hospital record chart holder is moved from place to place through the hallways of hospitals, and the like.

Other objects will appear hereinafter.

Construction A typical and preferred embodiment of the new portable hospital record chart holder is shown in the drawings, wherein it is generally indicated at 25, and comprises a supporting frame 26 which includes upright front corner posts 27 and rear corner posts 28 which are somewhat higher than the front corner posts 27 a lower front horizontal bar 29; and an upper rear horizontal frame bar 42 which extends between and interconnects the rear corner posts 28 at the top thereof. All of the parts of the supporting frame 26 described above may be .made of any suitable material such, for example, as chromium-plated tubular steel, or other suitable material.

A pair of supporting bars 30 are arranged at opposite sides of the supporting frame 26 and extend angularly upwardly from the lower horizontal front frame bar 29 to the upper end portions of the rear corner posts 28; the supporting bars 30 being attached at their lower ends to the lower front horizontal frame bar 29 and at their upper ends the supporting bars 30 are attached to the upper end portion of the rear corner posts 28. Each of the supporting bars 30 is generally L-shaped in cross section (FIGS. 20 and 21) and 'has formed integral therewith an upright notched arm 31 which extends at right angles to the body of the supporting bar, and bearing notches or recesses 32 are formed in each of the arms 31 at spaced intervals longitudinally thereof. A third supporting bar member 33 is arranged midway between and parallel to the supporting bars 38-31 at the center of the supporting frame 26. This supporting bar member 33 is generally U-shaped in cross section (FIGS. 4 and 19) and includes a pair of spaced notched arms 34 each of which is provided with longitudinally spaced notched bearing recesses 35.

The new hospital record chart holder apparatus is adapted for use with hospital record chart holders 36, each of which includes a base member 37 and a cover member 38 which are hingedly interconnected by hinge means 39 which includes hinge pintles each having an outer bearing end portion 40 which is swingingly mounted in one of the bearing notches 32 in the outer supporting frame bars 30-31. Similarly, each of the hinge pintles for the record chart holders 36 has an inner bearing end portion 41 which is swingingly mounted in one of the bearing notches 33-34 (FIGS. 4 and 19). As shown in the drawings there are two spaced but generally parallel rows or groups of the record chart holders 36 which are suspended vertically on the supporting bar members 30-31 and 33-34 within the supporting frame 26 and parallel to each other at staggered intervals vertically upwardly from the front of the supporting frame 26 to the rear thereof; the top of the supporting frame 26 being open to facilitate access to the record chart holders 36 for insertion and withdrawal thereof.

The central supporting frame bar 33-34 extends angularly upwardly between and is attached at its ends to a central front supporting frame post 43, which extends between the lower horizontal frame bar 29 and a horizontal frame shelf 44 on the supporting frame 26, and an upper central frame post 45 which extends between the horizontal shelf 44 and the upper horizontal frame bar 42.

The new portable hospital record chart holder includes snubbing means, generally indicated at 46, for snubbing the laterally outer edge portions of the hospital record chart holders 36 and holding them snubbed between the snubbing means 46 and stationary resilient snubber bar members 47 one of which is mounted at each side of the supporting frame 26 (FIGS. 1, 15 and 19). Each of the stationary resilient snubber bar members 47 is carried by a supporting bar 48 which is attached at its upper rear end to one of the rear upright corner frame posts 28 and is attached at its lower front end to one of the front upright corner posts '27, so that the stationary resilient snubber bar members 47 extend angularly upwardly between the front corner frame posts 27 and the rear front corner frame posts 28 below and paralleled to the outer notched supporting bars 30-31 (FIGS. 1 and 19).

As best shown in FIGS. 4, 5, 9, 10, l1, 12, 13, 14 and 15, the means 46 for snubbing the lateral outer edges of the record chart holder 36 extends angularly upwardly from the central front supporting post 43 to the central rear supporting post 45 between the two rows of hospital record chart holders 36 and generally parallel to the stationary resilient snubber bar members 47. The snubbing means 46 comprises an assembly of parts which includes a supporting bar member 49 which is arranged at the bottom of the assembly 46, and which has a downwardly angled mounting arm portion 50 at its lower end which is attached to the central front supporting post 43. The stationary supporting bar member 46 has an upwardly extending mounting arm portion 51 at its upper end which is attached to the central rear supporting post 45.

Disposed immediately above the stationary supporting bar 49 in the assembly 46 is a lower slidable resilient snubbing bar member 52 and immediately above the lower slidable resilient snubbing bar member 52 is a slidable carrier bar 53 for the lower slidable resilient snubbing bar member 52. This slidable carrier bar 53 has a depending longitudinally extending flange 54 at one side thereof and this depending flange 54 extends downwardly along one longitudinal side edge 55 of the lower slidable resilient snubbing bar member 52.

Disposed immediately above the slidable carrier bar 53-54, and disposed midway of the assembly 46 is a slidable operating bar member 56 for the movable parts of the assembly 46. This slidable operating member 56 has a shank portion 57 at its lower end and a slidable supporting bearing rod 58 is attached to the shank portion 57, as shown in FIG. 18. The supporting bearing rod 58 for the slidably operating bar member 56 is slidably mounted in bearing openings 59 which are formed in the central front supporting post 43 and the supporting bearing rod 58 has an enlarged head 60 thereon at its lower end. The supporting bearing rod 58 projects through a bearing opening 61 which is formed in an operating handle member 62, which includes a main body portion 63 which is pivotally mounted, its lower end, as at 64, on the front central post 43 (FIGS. 16, 17 and 18). The operating handle member 62 has a transversely extending finger grip portion 65 at its upper end to facilitate manual operation thereof, as will be described hereinafter.

Disposed immediately above the slidable operating bar member 56, in the assembly 46, is an upper slidable carrier bar member 66, which corresponds generally to the lower slidable carrier bar member 53-54, but differs therefrom in that the upper slidable carrier bar member 66 has an upwardly and longitudinally extending flange 67 at its laterally outer side. This upwardly and longitudinally extending flange 67 extends parallel to the longitudinal outer edge portion 68 of an upper resilient snubbing bar member 59 which, like the lower resilient snubbing bar member 52, may be made of rubber or other suitable resilient material. A flat metal bar 70 is disposed above the upper resilient snubbing bar member 69, to complete the main parts of the assembly 46.

As best shown in FIG. 14, the stationary supporting bar member 49 has longitudinally spaced holes 71 formed therein and correspondingly spaced holes 72 are provided in the uppermost flat metal bar member 70 for the passage of fastening elements, in the form of screws 73, which are adapted for the reception of threaded nuts 74 which are disposed below the stationary supporting bar member 49 in the assembly 46.

The lower resilient snubbing bar member 52 is provided with :a plurality of longitudinally spaced transversely extending slots 75 for the reception of the screws 73 and the lower slidable corner bar 53-54 is provided with similar and corresponding spaced transversely extending slots 76 for the passage of the screws 73. The slidably operating bar member 56 is provided with a plurality of longitudinally spaced and longitudinally extending slots 77 for the passage of the screws 73. The upper slidable carrier bar member 66-67 is provided with longitudinally spaced transversely extending slots 78 and the upper resilient snubbing bar member 69 is provided with correspondingly longitudinally spaced transversely extending slots 79 for the passage of the screws 73.

It will be noted (FIG. 14) that the lower slidable carrier bar member 53-54 has a pair of longitudinally .bar 56 and project above and below the latter into the bayonet slots 80-81 and 81-81 respectively.

In assembling the parts of the assembly 46, the upper resilient snubbing bar member 69 and the upper flanged carrier slide bar 66-67 for the upper resilient snubbing bar member 69 are attached together as a unit by means of suitable fastening elements, such as headed rivets, 83 which are inserted through aligned or registered holes 84 and 85 which are formed in the parts 69 and 66, respectively. Similarly, the lower resilient snubbing bar member 52 and the lower flanged slidable carrier bar member 53-54 are attached together as a unit by means of suitable fastening elements, such as headed rivets 86, which are extended through registered holes 87 and 88 which are formed in the parts 52 and 55, respectively.

Operation The use and operation of the new portable wheelbearing hospital record chart holder are as follows: The parts being assembled, as shown, two groups of the hospital record chart holders 36 may be swingingly suspended vertically in parallel and vertically staggered relationship in the supporting frame 26 by inserting the outer end portions 40 of their hinge pintles in the bearing notches in the outer notched supporting bars 30-31 and 30-31 and inserting the inner end portions 41 of the hinge pintles in the bearing notches 35 in the central notched supporting member 33-34.

When the new hospital record chart holders 36 are being used in an oflice, or at a nurses desk in a hospital, or like place, the resilient movable snubbing bar members 52 and 69 and their flanged slidable carrier bar members 55-54 and 66-67, respectively, are disposed in their inwardly retracted position in which the part are shown in FIGS. 4, 7, l0, l1 and 15, and the slidable operating bar 56 and its supporting bearing rod 58 are disposed in their inwardly retracted position, with the operating handle 62-63-65 therefor being disposed in raised position, as in full lines in FIG. 16, and as in FIGS. 17 and 18. At this time the laterally outer edge portions of the hospital chart record holders 36 are disposed in engagement with the stationary resilient snubbing bar members 47, as shown in FIGS. 15 and 19.

However, when it is desired to move the new portable hospital record chart holder 25 from one place to another through the hallways or corridors of a hospital, or like place, the hospital record chart holders 36 may be secured against swinging movement on their hinge pintles by manually grasping the finger grip arm 65 of the operating handle member 62-63-65 and moving the same on its pivot 64 from the position in which it is shown in full lines in FIG. 16 and in FIGS. 17 and 18, into the outwardly extended position in which it is shown in dotted lines in FIG. 16. During this movement the operating handle member 62-63-65 engages the headed outer end portion 60 of the supporting bearing rod 58 for the slidable operating member 56 and slides the latter outwardly and downwardly relative to the fixed or stationary supporting bar member 49. During this movement of the slidable operating bar member 56 the pins or studs 82 thereon move in the bayonet slots and 81, respectively, in the lower and upper flanged slidable carrier bars 53-54 and 66-67 for the lower and upper resilient snubbing bar members 52 and 69, respectively.

This movement of the pins or studs 82 in the bayonet slots 80 and 81 in the flanged carrier bars 53-54 and 66-67, respectively, causes the flanged carrier bar member 53-54 and 66-67 to move or shift laterally with the resilient snubbing bar members 69 and 52, respectively, thereon, and thus move or shift the resilient snubbing bar members 69 and 52 laterally in the assembly 46 relative to the stationary supporting bar member 49. In this manner the resilient snubbing bar members 52 and 69 are moved laterally outwardly into snubbing engagement with the inner marginal edge portions of the hospital record holders 36, thus snubbing the hospital record chart holder 36 between the stationary resilient snubber bar members 47 and the inner and laterally movable resilient snubbing bar members 52 and 69. In this manner the hospital record chart holders 36 are eflectively restrained against swinging movement on their hinge pintles when the new portable hospital record chart holder 25 is being moved from place to place through the hallways or corridors of a hospital or like place. Hence, the noise which would otherwise result from swinging movement and resulting clashing of the hospital record chart holders 36 on their hinge pintles is eliminated and the new portable hospital record chart holder 25 may be quietly and noiselessly moved from one place to another in a hospital or like place without objectionable noise.

After the new hospital record chart holder 25 has thus been moved from one place to another in a hospital, and it is desired to free the hospital record chart holders 36 for withdrawal from their notched supporting bars 30-31 and 33-34 this may readily be accomplished by grasping and moving the operating handle member 62-63-65- upwardly from the position in which it is. shown in dotted lines in FIG. 16 into the position in which it is shown in full lines in FIG. 16, and as shown in FIGS. 17 and 18. During this movement the operating handle member 62- 63-65 moves the slidably mounted supporting bearing rod 58 and attached slidable operating bar member 56 inwardly and upwardly and during this operation the pins or lugs 82 on the slidable operating bar member 56, working in the bayonet slots 80 and 81 in the flanged slidable carrier bars 53 and 66, respectively, urge the flanged slidable carrier bars 53 and 66, and the resilient snubber bar members 52 and 69 carried. thereby laterally inwardly. In this manner the slidable resilient snubbing bar members 52 and 69 are moved out of engagement with the adjacent inner marginal edge portions of the hospital record chart holders 36 which are thus freed for withdrawal from the notched supporting bar members 30-31 and 53-54.

It will thus be seen from the foregoing description, considered in conjunction with the accompanying drawings, that the present invention provides a new and improved portable hospital record chart holder having the desirable advantages and characteristics and accomplishing its intended objects including those hereinbefore pointed out and others which are inherent in the invention.
